Page 11: Introduction
The automatic IP connection keep-alive functionality maintains IP connections during bus idle times. The multi-port version of the L-IP combines the functionality of two L-IPs in one device. This device is equipped with a 100-BaseT Ethernet port (CEA-852) and up to four FT-10 ports (CEA-709).
Page 12 Figure 1: L-IP application example behind and without firewalls and NAT routers The L-IP series “C” models (product code ending with C) come with two Ethernet ports and the device setup can be done easily on the LCD display. The remote Wireshark packet capture feature is also available.
Page 13: L-Ip Redundant
The L-IP Redundant CEA-709/IP Router is a perfect solution for networks where a high reliability in the communication is required. It is a member of the L-IP family, based on the standard L-IP router and adds functionality which allows building redundant network infrastructure.
Page 14 CEA-709 network can be observed with status LEDs. For trouble-shooting, the Router supports the remote LPA (LOYTEC Protocol Analyzer) functionality so that the network can be analyzed from any PC connected to the Internet. With the L-IP Redundant CEA-709/IP Router, setting up a redundant network which is comfortable to maintain becomes an easy task.
Page 15: L-Ip Models
LOYTEC 1.2 L-IP Models This Section provides an overview of the different L-IP models in Table 1. This table identifies the different features of those models. Models that possess a certain feature have a check mark () in the respective column. If a feature is not available in the particular model, the column is left blank.
Page 16: What's New In L-Ip
Readme file. New L-IP Models The new L-IP models with their product code ending in “C” are now supported. Equipped with dual Ethernet, a built-in firewall and LCD display, these new models serve as a plug-in replacement for the older series “B” devices. Existing device backups can be used without modification.
Page 17 The L-IP series “C” models have the Wireshark packet capture feature. Using this feature local packet logs can be made and stored on the L-IP. It is also possible to connect a running Wireshark protocol analyzer on the PC to the L-IP and run a life packet capture.

4.7 Wiring 4.7.1 L-IP Every network segment connected to the L-IP needs to be terminated according to the rules found in the specification of the transceiver (see Chapter 11). Important: All used and unused ports must be properly terminated. LOYTEC recommends the use of the LOYTEC L-Term series network terminators (LT-13 or LT-33 respectively).
Page 34: L-Ip Redundant
If operated with bus loop monitoring enabled (loop port 1 and loop port 2 connected), both sides of the loop must be terminated at the L-IP terminals (see Figure 24). In this case two terminators for bus topology must be used.

If you configure multi-cast there may be some devices, which do not support this feature. In this case, the L-IP uses a hybrid scheme and sends unicast to those devices, which are not configured for multi-cast.

Installation and operation is plug&play if used in the smart switch mode, which can be set with the DIP switches. Please refer to Section 7.1.2 to set the L-IP into smart switch mode. After connecting the network cables, the L-IP can be powered up and it will start its switching application.

8.5 Remote LPA Operation The L-IP supports remote LPA access. This means that a CEA-709 protocol analyzer connected to the Ethernet network can connect to the L-IP and record all packets on the CEA-709 channel (FT-10). Our LPA-IP supports this sophisticated feature. The functionality is shown in Figure 96.

Page 105: Conventional Strategies For Redundancy
9.2.1 Bus Loop Monitoring To achieve redundancy against “3. Broken cable in the segment” (see Section 9.1.1) the L-IP allows building a ring structure by connecting both ends of the bus cable to the L-IP Redundant (see Figure 98). Assuming a redundant backbone.
Page 106: Router Redundancy
Now the L-IP Redundant is able to detect a cable fracture by permanently comparing the traffic on both sides of the bus: If the L-IP Redundant sees different traffic on its two terminals, the cable is deemed to be broken. In this case it starts to duplicate the traffic from loop port 1 to loop port 2 and vice versa.
Page 107 IP-852 channel. Further, the two routers must be linked by binding certain network variables, which are used for communication between the two paired L-IP Redundant routers. Please see Section 9.4.3.2 on how to configure the L-IP Redundant for router redundancy.
Page 108: Device And Network Monitoring
First a couple of channel quality parameters (e.g. bandwidth utilization, CRC error rate, etc.) are permanently monitored and their current values are provided as network variable (see Section 9.7), in the L-IP Redundant plug-in (see Section 9.5.4), and in the web interface (see Section 9.6.1).

Page 116: Device Status
The device status view is used to view the current state of the L-IP Redundant. To access the device status view click on the “L-IP Red. Status” icon on the left side of the L-IP Redundant Plug-In window (see Figure 111).
Page 117 Shows the name and the subsystem of the primary and – if present – the secondary device. By clicking on the “Wink” button the corresponding L-IP Redundant can be winked (see 4.4.9).

The channel statistics view is used to view statistic data accumulated by the L-IP Redundant for the two channels connected to the L-IP Redundant. To access the channel statistics view click on the “Channel Statistics” icon on the left side of the L-IP Redundant Plug-In window (see Figure 112).
Page 119: Alarm Log
Finally all statistic data can be cleared by pressing the “clear statistics” button. 9.5.5 Alarm Log Whenever an alarm occurs (e.g. “Ring open”) on the L-IP Redundant it is logged in the internal alarm log. The alarm log can hold up to 256 alarms.

Page 121: Node List Config
The node list is used for node monitoring (see Section 9.2.3). It must contain all the nodes, which should be monitored by the L-IP Redundant. If bus loop monitoring is used the order of the nodes in the list should represent the order of the nodes along the bus to be able to detect the point of fracture in case of a cable break: The node with index 1 must be the node closest to loop port 1 while the last node in the list must be the node closest to loop port 2.

LonMark alarming is supported via nvoAlarm (SNVT_alarm) and nvoAlarm_2 (SNVT_alarm_2). This allows devices supporting the LonMark alarm notifier profile (e.g. i.LON 100) to receive alarms generated by the L-IP Redundant and react with a defined action (e.g. send an email). By supporting both alarm SNVTs, SNVT_alarm and SNVT_alarm_2, legacy and state-of-the-art alarm handling is supported.

The TP-1250 uses transformers for galvanic isolation. The topology of a TP-1250 network is a bus. Thus, both ends of the bus cable need to be terminated. LOYTEC recommends using its L-TERM network terminators (LT-13) for network termination (see Figure 140).

Page 147: Redundant Ethernet
11.4 Redundant Ethernet 11.4.1 Ethernet Cabling Options The L-IP series “C” models are equipped with two Ethernet ports, which are connected to an internal Ethernet switch. This allows for advanced cabling options to reduce cabling costs or to increase network resilience. For this discussion, the term upstream is used to designate the direction towards the network, which the devices are connected to.
Page 148 Please note, that this is a feature of the switch, not of the L-IP, so that LOYTEC cannot give a guarantee that this will work with a particular switch model. In no case redundant cabling options will work with unmanaged switches.
